Assange allegedly had sex twice with another woman in her 20s, named as Jessica, at her home west of the city three days later, the first time with a condom and the second without protection, after he met her at the seminar.

She has alleged he refused to wear a condom during their second sexual encounter.

Assange is said to insist the sex with both women was consensual.

They went to a Stockholm police station on August 20 where they reportedly said they were seeking advice on how to proceed with a complaint by the younger woman against Assange.

A duty prosecuting attorney is said to have agreed Assange should be sought on suspicion of rape but the chief prosecutor later dismissed the alleged rape charge.
